Purpose: To report a case of multiple retinal capillary hemangioma associated with neurofibromatosis type 1 and resulting neovascularglaucoma.Case summary: A 13-year-old boy was admitted with complaint of visual disturbance and dull pain in his left eye which had beguntwo weeks prior. Lisch nodules were observed in his left iris and corneal opacity with neovascularization of the iris and anglewere detected in the same eye. Multiple retinal capillary hemangiomas with increased tortuosity and congestion of feeding retinalvessels were observed on the upper equator of the left retina; in addition, vitreous hemorrhage was observed. There were noother abnormalities except iris mammillations in the right eye. Numerous café au lait macules were observed on the patient’s entirebody. He also exhibited axillary freckling. On brain magnetic resonance imaging, T2-weighted signal intensity was increasedin the basal ganglia, left thalamus, and cerebellar white matter; however, no vessel abnormalities were observed on magneticresonance angiography. High intraocular pressure (IOP) persisted despite the use of IOP lowering agents and IOP was normalizedafter trabeculectomy with mitomycin C administration. Conclusions This case shows that multiple retinal capillary hemangiomas can be accompanied by neurofibromatosis type 1,which may result in neovascular glaucoma.

Pulmonary metastasis occurs frequently in patients with gestational choriocarcinoma and most of these patients achieve remission with chemotherapy alone. Thus, the indications for surgical intervention are limited, but in appropriately selected patients, resection of a chemotherapy-resistant lung lesion can be curative. We have experienced that pulmonary metastatic choriocarcinoma in a drug-resistant patient was cured by pulmonary resection. So we report this case with a brief review of literatures.

Multiple involvement of arterial fibromuscular dysplasia is unusal and such a case is quite limited in the literature. We present a case of multiple arterial fibromuscular dysplasia with aneurysm formation in a 38-year-old non-hypertensive man. Angiographic study showed multiple aneurysmal dilatations of the right renal, superior mesenteric, celiac axis, and left colic arteries. The resected right kidney demonstrated an aneurysm of the main renal artery and extensive infarction in the midportion of the renal parenchyma. The segmentally resected superior mesenteric artery disclosed a similar nature of aneurysm occluded by recent thrombi. Microscopically, all the resected arterial walls showed both intimal and medial fibroplasia together with periadventitial fibrosis resulting in marked narrowing of the lumen and subsequent thrombus formation.

A 5-year-old Labrador Retriever presented with a subcutaneous mass on the right scapular region with localized calor. On magnetic resonance imaging (MRI), a heterogeneously hypointense mass was seen on T1-weighted images (WI) and hyperintense on T2WI and fat-suppressed T2WI with marginal contrast enhancement on postcontrast T1WI and invasion into the surrounding tissue. Histopathological examination of the mass confirmed subcutaneous mast cell tumor (MCT) infiltrating to the adjacent subcutaneous fat. This is the first report to describe the MRI findings of subcutaneous MCT in veterinary medicine. This study suggests that MRI may help evaluate the extent of invasion of subcutaneous MCT.

PURPOSE: The purpose of this research was to determine the effects of a safety management program on safety accident-related knowledge, attitude and behavior of elementary school students in Korea. METHODS: This study adopted nonequivalent control group pretest-posttest design. The number of subjects was 34 in the experimental group and 31 in the control group. The safety management program was performed for approximately 50 minutes each session, once a week for 8 weeks. Data were collected from March 14th to June 23th, 2006, and analyzed by chi2 test and independent t-test with SPSS WIN 16.0. RESULTS: There were statistically significant differences in safety-related knowledge (t=3.010, p=.006) and behavior (t=18.833, p=.001) between the experimental group and the control group. The score of attitude was different between the experimental group and the control group but the difference was not statistically significant. CONCLUSION: The safety management program used in this study was appropriate for elemental school students and affected safety-related knowledge and behavior of elementary school students. Therefore safety education should be provided systematically for elementary schools over the whole country.

Chronic bronchiolitis is a condition associated with cigarette smoking, and later associated with pulmonary parenchymal alteration and progressive deterioration of lung function. Early respiratory bronchiolitis was produced in Sprague-Dawley rats by indirect inhalation of cigarette smoke daily in a smoke exposure chamber designed by authors for 1 month. Experimental group A (n=5) was sacrificed after having smoked 30 cigarettes, group B (n=5) after 80 cigarette, and group C (n=7) after 140 cigarettes, respectively. Examination of morphologic changes in the lungs was done on light microscope, transmission and scanning electron microscopes. Light microscopically, increase in number of goblet cells in the bronchial mucosa, brown-pigmented macrophages in the alveoli, multifocal alveolar collapse adjacent to the bronchioles, dilatation of alveolar ducts and alveolar spaces were observed. Transmission electron microscopically, irregularly shaped Clara cells, alveolar wall collapse, and focally type I epithelial cell injury were seen. Scanning electron microscopically, scattered alveolar collapse, irregular dilatation of alveolar ducts, alveolar spaces and interalveolar pores (pores of Kohn) were seen. The terminal and respiratory bronchioles showed morphological alteration of Clara cells, but no evidence of cellular bronchiolitis or bronchiolar obstruction. We conclude that sidestream smoke induces an early respiratory bronchiolitis including aggregates of brown pigmented macrophages and varying degrees of structural alteration of adjacent pulmonary parenchyma.

A group of 68 men who visited Urology Department of Severance hospital, including 11 patients with prostatitis and 57 patients with infertility were investigated for HBsAg from the specimen of serum, saliva and semen. HBsAg was detected by using a highly sensitive radioimmunoassay technique. The following results were obtained. 1. A case of 11 patients with prostatitis (9%) and 6 cases of 57 patients with infertility (10.5%) were HBsAg-positive in serum. 2. Of the 7 cases being HBsAg-positive in serum, 5 cases were HBsAg-positive in saliva (71%) and 3 cases in semen (43%) . 3. Type B hepatitis may be transmitted by parental, oral and probably venereal routes.
